ABSOLUTE MAXIMUM RATINGS at T A = +25°C Supply Voltage, V CC ............................ 28 V Reverse Battery Voltage, V RCC ........... -35 V Magnetic Flux Density, B .......... Unlimited Output OFF Voltage, V OUT .................. 28 V Reverse Output Voltage, V OUT ........... -0.5 V Continuous Output Current, I OUT ...... 25 mA Operating Temperature Range, T A Suffix ‘E–’ .................. -40 °C to +85°C Suffix ‘L–’ ................ -40 °C to +150°C Storage Temperature Range, T S .............................. -65°C to +170°C These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150 °C, and are more stable with both temperature and supply voltage changes. The unipolar switching characteristic makes these devices ideal for use with a simple bar or rod magnet. The four basic devices (3141, 3142, 3143, and 3144) are identical except for magnetic switch points. Each device includes a voltage regulator for operation with supply voltages of 4.5 to 24 volts, reverse battery protection diode, quadratic Hall-voltage generator, temperature compensation circuitry, small- signal amplifier, Schmitt trigger, and an open-collector output to sink up to 25 mA. With suitable output pull up, they can be used with bipolar or CMOS logic circuits. The A3141– and A3142– are im- proved replacements for the UGN/UGS3140–; the A3144– is the improved replacement for the UGN/UGS3120–. The first character of the part number suffix determines the device operating temperature range. Suffix ‘E–’ is for the automotive and industrial temperature range of -40 °C to +85°C. Suffix ‘L–’ is for the automotive and military temperature range of -40 °C to +150°C. Three package styles provide a magnetically optimized package for most applications. Suffix ‘–LT’ is a miniature SOT89/TO-243AA transistor package for surface-mount applications; suffix ‘–UA’ is a three-lead ultra-mini-SIP. FEATURES and BENEFITS s Superior Temp.
